To @ZZ whom, it may concern:

Be it known that I, PERCY VAREHAM', of Brooklyn, in the county ofJackson and State of Michigan, have invented certain new and usefulImprovements in Revolvers 5 and I do hereby declare the following to bea full,clear, and exact description of the invention, -such as willenable others skilled in the art to which it appertains to make and usethe same.

The invention relates to improvements in revolvers.

The object of the present invention is to improve the construction ofrevolvers and to provide one which may be conveniently loaded and inwhich the break of the barrel will be controlled by efflcient lockingdevices.

rlhe invention consists in the construction and novel combination andarrangement of parts, as hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

For a full understanding of the merits and advantages of the inventionreference is to be had to the accompanying drawings and the followingdescription.

The improvement is susceptible of various changes in the form,proportion, and the minor details of construction without departing from.the principle or sacrificing any of the advantages thereof, and to afull disclosure of the invention an adaptation thereof is shown in theaccompanying drawings, in which- Figure 1 is a longitudinal sectionalview of a revolver constructed in accordance with this invention, thedotted lines showing the barrel turned down and the operation of the eX-tractor. Fig. 2 is a detail perspective view of the barrel-catch. Fig. 3is a detail perspective view of the block carrying the latch whichcooperates with the barrel-catch. Fig. 4 is a rear view of the cylinderand shell-extractor. Fig. 5 is a perspective view of the trigger,hammer-lifting pawl, and hand. Fig. 6 is a perspective view of thelifting-lever for operating the extractor and its retaining-dog. Fig. 7is a detail view of the post upon which the cylinder is mounted. Fig. 8is a detail view of the extractor rod or stem. Fig. 9 is a detailsection of the barrel-strap, catch, and adj unctive parts.

Corresponding and like parts are referred to in the followingdescriptionand indicated in the several views of the drawings by the same referencecharacters.

The numeral 1 designates a barrel of any preferred form of construction,having extending longitudinally along the top thereof a rib 2, carryinga sight 3 at the front end. The barrel 1 is connected to the frame 4 bya hinge-joint 5,which is of the usual construction in such devices, andsupported by the barrel-section is a revolving cylinder 6,which receivesthe cartridges in a well-known man'- ner. In the barrel-strap 7, overthe top of the cylinder 6, is a barrel-catch S, consisting of a bolt9,with a reduced stein 10, encircled by a coiled spring 11. A tongue 12extends rearwardly from the bolt 9 and has a recess 13 in the top nearits rear end, and about midway the ends of the catch is a cross-arm 15,

which extends through a slot formed in the barrel-strap and is providedwith vmilled lugs 16 at its extremities,which come upon opposite sidesof the strap 7 and are adapted to be engaged by the fingers of the handwhen operating the catch 8. The cross-arm 15 moves in a slot 14,extending transversely through the strap 7. In the rear of the catch Sis a latch 17 having a hook 1S at its front end to enter the recess 13and secure the barrel in its firing position. The said latch is mountedin a block 19, secured to the standing breech in the rear of thebarrel-strap 7, and is pivoted in a slot 2O and has its rear endprojecting beyond the said barrel-strap for engagement by the thumb ofthe operator. On the top of the standing breechis a sight 21,whichalines with the sight 3 on the front end of the rib 2.

The catch 8, latch 17, and the adj unctive and cooperating devices areintended to lock and release the barrel-section from the frame of therevolver.

When the cross-arm 15 is at the limit of its rearward movement in theslot 14, the latch 17 is interlocked with the catch S, and to releasethe barrel itis first necessary to press down upon the projecting end ofthe latch 17, thereby liberating the catch 8,'Which is moved forward bygripping the lugs 1G, after which the barrel can be turned down, asshown by the dotted lines in Fig. 1.

The cylinder 6 is mounted on a tubular post IOO 22, secured at its frontend, which has an enlarged portion 22c in a pendent portion 25g of thebarrel and inclosing a spring 24, confined between the front portion ofthe extractorrod 23 and the rear end of the post. A threaded shoulder ais provided about midway of the post, and the cylinder has the front endof its bore correspondingly threaded at ZJ to pass by the threadedshoulder a and retain the cylinder in place upon the post when thebarrelis turned down. The cylinder can be removed by turning the barreldown and grasping and rotating the cylinder backward until its threadedpart b clears the threaded shoulder a. An extractor 26 is secured to therear end of the rod or stem 23 and fits snugly within a depression inthe rear end of the cylinder and has notches 27 corresponding inposition and size with the chambers of the cylinder. The ratchet-teethor shoulders 32, which cooperate with the hand 43, are formed on therear face of the extractor.

A disk 28 is mounted on the pin upon which the barrel turns and hasaprojection 29,which enters a slot in the front end of the post 22 andextends across the path of the rod 23, so as to move the latter and theextractor when turning down the barrel. A groove or channel 30 is formedin one face of the disk 28 and receives a sliding dog 3l. This dog is ofless width than the groove 30 and has extensions c and d at its ends,the outer extension c being beveled on its exposed end to be engaged bythe lower end of the part 25 to release the dog from the front end ofthe frame 4, thereby permitting the disk and the extractor to return toa normal position. The inner extension d engages with a stop e,projecting` from a side of the groove 30, and limits the outwardmovement of the dog. Aspring f is interposed between the stop e and theextension c and serves to normally hold the dog 3l projected, wherebythe extension c is caused to engage with the front end of the frame 4and hold the disk 28 station ary While turning the barrel, whereby theejector is actuated and removes the empty shells from the cylinder. Justprior to the barrel reaching the limit of its downward movement thelower rear 'end of the pendent portion 25 engages with the beveled endof the extension c and presses the dog 3l inward, thereby liberating thedisk and the ejector and permitting the latter to return to a normalposition by the action of the spring 24 regaining itself, vas will bereadily understood.

The lock comprises a hammer 33, coacting with a iiring-pin 34, and atthe rear of the hammer is connected a stirrup 35, to which is attachedthe main spring 36, engaged and controlled by a lower strain-screw 37.The said'hammer 33 is pivoted at 38, and in rear and slightly below itspivotal point are two Sear-notches 39 and 40. A trigger 4l is locatedunder the hammer and inclosed by a guard 42. To said trigger is movablyattached Va hand 43, which operates the cylinder 6 and is engaged by aspring 44 to maintain the contact of the hand with the ratchetteeth orshoulders 32, whereby a synchronous action of the hammer, cylinder, andextractor is secured. Also connected to the trigger is a hammer-liftingpawl 45, havinga rear notch 46 in its upper end to engagea projection onthe lower part of the hammer. A sear 47 has the front end of itshorizontal arm entering a recess in the heel of the trigger to beoperated, whereby when pressing upon the trigger the upper end of thevertical arm of the scar engages either one or the other of thesearnotches 39and 40.. Bearing against the sear is a spring 48, and alsoin engagement with the lower portion of the hammer is a'rebounding-spring 49, forming a part of the spring 48. Said trigger atthe front is also provided with a spring 50 for well-known purposes, asalso has the firing-pin 34.

`In operation when the hammer is drawn backwardly a resistance of courseis offered by the main spring 36, and the scar 47 and rebounding-spring49 ride over the lower rear portion of the hammer, and when the trigger41 is operated to release the hammer it is caused to rebound from thefiring-pin by the said rebounding-spring and is caught by the sear andset half-cocked. When the hammer is thrown backward by the rebound orotherwise, the firing-pin is moved rearward by its spring and isnormally out of contact with the cartridges, thereby avoiding accidentsfrom a cartridge being exploded by striking the hammer involuntarilyagainst an obstruction as is frequently the case when the firing-pinbears against a cartridge.

Having thus described the invention, what is claimed as new is l. In arevolver or gun, the combination of a barrel movably attached to aframe, aspringactuated barrel-catch-having a rearwardlyprojectingrecessed tongue, andalatch in rear of said tongue to engage the latter,and pro` vided with an extended end for releasing the bolt,substantially as and for the purpose specified.

2. In a revolver or gun, the combination of a spring-actuatedbarrel-catch, and a latch to engage the same and having arearwardlyprojecting end and means for operating the catch and lockingthe parts, substantially as and for the purpose specified.

3. In a revolver or gun, the combination of IOO IIO

a barrel hinged to a frame, a spring-actuated Y catch carried in thebarrel-strap and having a rearwardly-projecting tongue with a recesstherein, a cross-arm attached to said catch and provided with lugs atits outer ends, a block in rear of said tongue, and a latch movablymounted in said block and having a rearwardly-projecting end,substantially as and for the purpose specified.

4. In a revolver,the combination of aframe, a barrel hinged tothe frame,means for securing the barrel to the' frame in a firing position, ashell-extractor, a disk mounted concentric with the hinge-joint of thebarrel with the frame and adapted to aotuate the shellextractor, andhaving a groove in one face in the rear of the pivotal Connection of thedisk with the frame, and having a stop extending into the groove fromthe front Wall thereof, a dog slidably mounted in the aforesaid grooveand having end extensions, the inner extension engaging with theaforesaid stop to limit the outward movement of the dog and the outerextension projecting beyond the disk and beveled 011 its outer end, anda spring interposed between the stop and the outer extension,substantially as and for the purpose specified.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
